SAFETY-GUARD FOR RAI LWAYS.

SPECIFICATION forming part of Letters Patent No. 279,700, dated June 19,1883. Application filed February. 15, 1883. (No model.) A

To all whom it may concern:

ings, which form a part of this specification.

This invention relates to certain new and useful improvements in theconstruction of safety railway-guards, the object of the invention beingto so construct a railway as to guard the approaches to bridges,trestles, 850., and to effectually prevent the train from being derailedand to insure its passage over the main track.

To that end the invention consists in the peculiar construction andarrangement of certain points and guard-rails, in combination with themain rail, allas more fully hereinafter set forth.

Figure l is a plan view; showing arrangement of points, guards, andrails as laid at the approach to a bridge or trestle. Fig. 2 is a sideelevation 'of one of the inclined points. Fig. 3 is a section on theline 00 m, Fig. 1.

In the accompanying drawings, A A represent the main-track rails, whichare laid in the usual manner.

B B represent the inner guard-rails, the surfaces of which should behigher than the surfaces of the main rails. These guard-rails are placedquite close to the main rails, their ends converging toward each other,as in the usual manner; but instead of having the ends square I preferto round them oif in any suitable manner, in order that they may notcatch the brake-chains or staff of a passing train.

Between the guard-rails B and the main rails A are secured thesafety-points D, substantially of the same construction as thosedescribed in Patent No. 204,710 to James Briody, June 11, 1878, with theexception that the heel of this point is extended, and the head and webof each are cut away upon a grad-j ual incline from the foot of the railto the face, as shown in Fig. 2.

E E represent the outer guard-rails, which are laid upon and secured tothe ties close to the main rail at the immediate approach to the bridgeor trestle, while their other ends are curved and diverge from the mainrails, and are carried back as far as may be desired; and the upperfaces or tread of these guardtrestle, are inclined from the foot to thehead of the rail from which the point is made, similar to the point D,as above described, while the tread at the opposite end of this point isbrought close to the inner sides of the guardrail E, and at about thesame level therewith, and are so placed that the inner edges of thepoints and the guard-rails will be almost upon a direct line. V

In practice, a train passing over the road in the direction indicated bythe arrow, should it by any cause be thrown from the track or derailed,the wheels upon one side of the train would be between the main rails,while upon the opposite side they would be between the main rails andthe outer guards, E, and rest upon the ties. As the train in thiscondition approaches the bridge or. trestle the wheels which are betweenthe outer guard-rails and the main rail would be compelled to run up theinclined point F, over the same, and upon the tread of the outerguard-rail upon that side, and in the further progress of the train thewheels upon the opposite side will be compelled to ride up the inclinedheel of the points D, and from thence out onto the tread of the innerguard-rail, B. The wheels which have reached this point are now upon thetread of the guardrails which are above the surface of the main rail.Now, in the further progress of the train, the inner guardrail compelsthe wheel which is running upon it to shift over to the tread of themain rail. This movement draws the opposite wheel across the tread ofthe opposite main rail, the flange dropping between it and its adjacentinner guard-rail.

What I claim as my invention is In combination with the main-track railsA A, the inner guard-rails, B, and the diverging outer rails, E,arranged higher than the main rails, the points D, arranged between therails B and A, and inclined points F, ar-- ranged between the rails Eand A, the whole constructed, arranged, and operating substantially inthe manner and for the purposes set forth.
